HEATING-DRUM.

Specification of Letters Patent.

Patented March 12, 1907.

Application filed August 2'7, 1906- Serial No. 332,165.

To all whom it may concern- Be it known that I, FREDRIOH J. KoBUsoH, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Heating- Drums, of which the following is a speoification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to that form of heating-drum wherein a cylindrical chamber is located in a vertical line of stovepipe, and

which chamber or drum is provided with a plurality of baffle-plates which tend to retard the passage of smoke and other products of combustion through the drum, which action necessarily results in a radiation of the heat from said smoke and products of combustion.

To the above purposes my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in the claim, and illustrated in the accompanying drawings, in which I Figure 1 is a vertical section taken through the center of my improved heating-drum. Fig. 2 is a side elevation of the conical deflectors, which are positioned on the interior of the heatingdrum. Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 1.

Referring by numerals to the accompanying drawings, 1 designates the body of the drum, which is preferably constructed of sheet metal in cylindrical form, its lower end 2 being tapered downwardly and terminating in the short cylindrical section 3, which when the drum is in use is positioned on the end of a length of stovepipe.

The upper end of the drum is closed by a conical member 4, the upper end of which terminates in a short tubular section 5, which when the drum is in use is located in the lower end of a length of stovepipe in vertical alinement with the length of stovepipe in which the member 3 is inserted.

Rigidly fixed to the inner face of the upper edge of the cylinder 1 is a baffle-ring 6, the lower end of which is somewhat smaller in diameter than the upper end thereof, and said lower end terminates a short distance above the center of the cylindrical body 1.

Formed through the upper end of the ring 6 is a row of apertures 7. Fixed to the lower end of the ring 6 and depending therefrom is a series of straps 8, to the lower ends of which is fixed a conical deflector 9, constructed, preferably, of sheet metal, the diameter of which is somewhat less than the interior diameter of the body 1, and said deflector 9 is concentrically arranged on the interior of the member 1 a short distance above the lower end 2 thereof. Fixed to and extending upwardly from the lower end of the ring 3 is a series of supports 10, to the upper ends of which is fixed the lower end of a conical deflector 11 the same being concentrically arranged within the member 1 and with its base in approximate alinement with the row of perforations 7.

When my improved heating-drum is in use, the smoke and other products of combustion passing into the lower end of said drum will strike the deflector 9 and will be thrown or deflected thereby outwardly against the wall of the heater and will pass upwardly along the same and will finally pass between the tapered ring 6 and the upper portion of the member 1 and will finally discharge upwardly through the apertures 7.

Any smoke or products of combustion that pass upwardly through the lower end of the ring 6 will strike against the deflector 11 and be deflected thereby outwardly to mingle with the products of combustion discharging through the apertures 7, and said products of combustion will finally discharge upwardly through the stovepipe fixed to the upper end of the drum' The heat from the smoke and gases arising through the drum will naturally be thrown off or radiated, as said smoke and gases are retarded in their passage through the drum, and any soot that may be drawn upwardly into the drum by the natural draft therethrough will strike against the various deflectors, and thus be prevented from discharging through the stovepipe above said drum.

A heating-drum of my improved construction is very light, strong, and durable, can be easily and cheaply manufactured, and is very efficient in use.

I claim- A heatingdrum, constructed with a cylindrical body, asheet-metal ring rigidly fixed within and to the top of said body, the bottom of which ring is smaller in diameter than the top, -there being a row of perforations f In testimony whereof I have signed my formed through the ring adjacent the top name to this specification in presence of tWo thereof, a conical deflector concentrically 'arsubscribing itnesses.

ranged in the drum beneath the ring, and a FREDRIOH KOBUSCH.

conical deflector concentrically arranged in Witnesses: the drum above the ring, which deflectors M. P. SMITH, are of the same size and shape. 1 E. L. WALLACE.
